INK FOR MARKING CIGARS OR TOBACCO.

SPECIFICATION forming part of Letters Patent N 0. 646,122, dated March.2'7, 1900.

Application filed Augus 15, 1899. Serial No. 727,281- (No specimens.)

To LLZZ' whom it may concern.-

Be it known that I, EMANUEL KLEIN, a citizen of the United States, and aresident of New York city, county and State of New York, have inventednew and useful Improvements in Coloring Compositions, of which thefollowing is a specification.

This invention relates to a coloring composition adapted to be appliedfor marking tobacco and for stenciling, painting, and printingtrade-marks or names upon cigars, cigarettes, and the like, so that thedesign subsequently appears incombustible upon the ashes. Thecomposition is, however, also well adapted for application to ceramicware, textiles, and other objects.

In carrying my invention into effect I proceed as follows:

First. Lanolin (or its equivalents, such as cholesterin, isocholesterin,or ceryl alcohol) is heated in an open vessel communicating with a worm.White vapors will escape, which are liquefied in the worm and may beutilized for difierent purposes. Gradually the vapors in the vessel willbecome stronger and will suddenly ignite,when the vessel is closed by ahermetic lid, the heat-supply withdrawn, and the contents are allowed tocool. This operation is repeated several times, so that the residue whenallowed to cool becomes an inspissated mass, which will dry quickly, isodorless, of dark-brown color, and possesses great adhesiveness. Ifdesired, some quickly-drying, non-poisonous, tasteless, and odorlessoils or fats may be mixed with the lanolin, and the resulting compoundmay be bleached.

Second. An incombustible inorganic or organic color or pigment whichwill retain its appearance under the influence of heat is prepared. If abrown red is desired, it may be obtained as follows: Carbonate of ironor black oxid of iron (which are equivalents for the purpose of thisinvention) is subjected to a glow heat in a closed fireproof cruciblefor about half an hour and is then cooled and ground.

Third. About forty five per cent.,by weight, of the prepared lanolin iscooked for several minutes with about fifty-four per cent. of theprepared coloring-matter. The mass is allowed to cool and is ground. Ifdesired, one per cent. of a suitable drier, such as boracic' protoxid ofmanganese, may be added.

Fourth. The composition thus made is applied in suitable design by abrush, stamp, stencil, or printing-press to tobacco and to the wrappersof cigars, cigarettes, or similar articles. When the tobacco isconsumed, the design will be retained in conspicuous color upon theashes,whether they are light or dark.

The composition will set quickly, is indelible in water, and is notconsumed by fire. The particular merit of the prepared lanolin base isthat it intimately unites with the tobacco, so that it fixes the color.At the same time the lanolin will be consumed readily by the firewithout giving 0E odors or impairing the burning quality of the tobacco.

What I claim is 1. The process of producingacoloring composition, whichconsists in inspissating lanolin, mixing it in a liquid state with apigment, and cooling the mixture, substantially as specified.

2. The process of producinga coloring com= position, which consists ininspissating lanolin, subjecting carbonate of iron to a glow heat,mixing it with the inspissated lanolin, and cooling and grinding themixture, substantially as specified.
